Abstract

The utility model discloses a simple optocoupler detector based on a time-base integrated chip. The simple optocoupler detector comprises an optocoupler being detected, the time-base integrated chip, first to fourth resistors, a first capacitor, a second capacitor and a light emitting diode. A special tool for detecting the optocoupler is made simply and effectively by adopting the time-base integrated chip and a plurality of the resistors and the capacitors at the periphery, and whether the optocoupler is good or bad is judged according to luminance or non-luminance of the light emitting diode. The simple optocoupler detector disclosed by the utility model is low in cost, can detect the optocoupler quickly and effectively, and saves time and labor, thereby being conducive to popularization.

Description
